Siarnaq, Moon of Saturn

Siarnaq is a Moon that orbits round the planet Saturn. It is also know by other designations, SXXIX, S/2000 S3. Its mass is estimated/calculated at being 38,965,379,260,527,000 kg. Its density has been calculated at being 2.3. Its volume is 33510.

Siarnaq was discovered on 23 September 2000 by Brett J. Gladman, John J. Kavelaars, Jean-Marc Petit, Hans Scholl, Matthew J. Holman, Brian G. Marsden, Phillip D. Nicholson, and Joseph A. Burns.

The orbital period, i.e. the period it takes to complete an orbit round Saturn is 896 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A..

The Equatorial Radius of the object is 20km. The Equatorial Radius is based on the assumption of the Albedo value. The value is the radius in km of the said object at the Equator.

The albedo of the object is 0.06. The Albedo is the amount of radiation that is reflected back into space by the object.

The Escape Velocity of the object is 58 km/h. The Escape Velocity is the speed an object needs to be travelling in order to break free from the objects gravity. The larger an object is, the more velocity (speed) is needed to break free from the object.The Semi-Major Axis of the orbit is 17530, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Siarnaq is 125.7 km. The surface area of Siarnaq is 5,026.55. The surface gravity of the said item is 0.007. The Mean orbit velocity, that is the speed at which it orbits is 5038.20 km/h. The is the average distance in km of the object is from its parent 18015400.00.

The orbital inclination, the angle at which Siarnaq orbits in relation to the orbital plane is 45.6 degrees. The orbital eccentricity is 0.4052, it is the degree at which Siarnaq orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
